IPC: G21C7/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To ensure thermal margin and improve economy in a fuel assembly which average enrichment is raised for high burnup or prolonging operation cycles. SOLUTION: A fuel assembly 8 is arranged with fuel rods 1, 2 and 3 (enrichment of 4.9%, 4% and 3%), partial length fuel rods 1P and 2P (enrichment of 4.9% and 4%) and gadolinia fuel rods (enrichment of 4% and gadolinia concentration of 4%) in 9×9 square grid. The average enrichment of each fuel rod and average gadolinia concentration in the control rod side region 21 are set lower than those in the counter control rod side region 22. The gadolinia fuel rods are not distributed in the (2, 2), (2, 3) and (3, 2), where (1, 1) is the fuel rod position at the corner of the control rod 6. Thus, the fuel rods in the control rod side region 21 burn in advance in the beginning to the middle of fuel life and in the case that the control rod 6 is withdrawn during operation in the middle to ending of life, power rise does not exceed by the withdrawal and thermal margin is assured.

Abstract: PURPOSE:To make the blowoff of a fluid intermittent, to execute a spray to a user and to improve a massage effect by giving the torque around a shaft to a rotary body in receiving the pressure of a flow from an inlet up to an outlet. CONSTITUTION:The fluid supplied from a fluid supplying source is introduced through a fluid introduction port 10 into a massager 7 main body, and the duct 16 of a rotor 14, in which an inlet 16a is closely faced to the introduction port 10, is made flow attending with the flow, a part of the duct 16 receives the fluid pressure to rotate the rotor 14, and thereby, the rotary body 14 supported rotatably and pivotally with the supporting part 13 of the massager 7 main body is rotated. Then, the position of the outlet of the duct 16 is moved, and the rotary body 14 is faced to the inlet edge 11a of the fluid blowing-off passage 11 of the massager 7 main body at every rotation. Since the fluid taking the duct 16 flows into the fluid blowing-off passage 11, the fluid is blown off from the head of the passage 11 to the user only at this time, and the massage is executed.

Title: Gate controlling circuit for gate turn-off thyristor
Inventor: SATOU MASAYOSHI
IPC: H03K17/732
Filed: 1981-06-08
Abstract: PURPOSE:To reduce the loss of a thyristor provided in a circuit for turning a gate turn-off thyristor (GTO) through the constitution of parallel connected thyristors. CONSTITUTION:When a GTO1 turns off, a transistor 7 turns on and thyristors 81 and 82 turn on. Thus, an inverse current flows between the cathode and gate of the GTO1 and the GTO1 turns off. Since the thyristors 81 and 82 are parallel connection of small capacity of thyristors, the loss of the thyristors 81 and 82 caused when an off-gate current flows to the GTO1 can be decreased.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a useful liquid for cleaning foreign matters or the like stuck to sliding faces of the magnetic head of a magnetic recording and reproducing device by making the liquid contain a fluorine-containing ether compound. SOLUTION: A compound represented by the formula: Cn F2n+1 O-Cm H2m+1 is incorporated. In the formula, n and m are each 1-5. This compound is not only excellent in cleaning properties but also well retained on the surfaces cleaned thus holding cleaning effects. And it also exhibits water-repellent properties and is less hygroscopic leaving no water on the surfaces cleaned. Therefore it does not suffer for oxidation of a magnetic head or the like or re-sticking of dust or the like caused by water absorbed in a cleaning liquid. Further, it does not cause any troubles from the viewpoint of the global environmental protection and is not inflammable and is easy to handle. If necessary, is further added a fluorine-containing resin, which is retained as a film on the surfaces of magnetic head tracks and the like preventing re-sticking of a contaminants to keep the cleaning effects.

Filed: 1983-05-19
Abstract: PURPOSE:To prevent abnormal noise from being produced while relaxing the surging of a compressor by inserting into a large diameter coil a small diameter coil having an outer diameter formed slightly larger than the internal diameter of the large diameter coil. CONSTITUTION:A small diameter coil 42 of a double coil spring 4 is formed slightly larger in its outer diameter than the internal diameter of a large diameter coil 41. They are adapted to make close contact with each other at all positions on respective effective wound parts. For example, the pitch of the small diameter coil is formed larger by about 0.1-0.5mm. than that of the large diameter coil 41. When suspending a compressor body 5 by means of this double coil spring 4, the outer peripheral part of the small diameter coil 42 makes close contact with the inner peripheral part of the large diameter coil 41 at all positions on the effective wound part A of the double coil spring. Hereby, the large and small diameter coils are reduced in their mutual resonance due to a damper effect.
